Yeah nah, we have exactly zero plans for a meat-shield style strategy of that sort. Our "soft" support (US + NATO provide the bang and the buck, while Ukraine provides the blood) has worked out the way it has in Ukraine because, well, the conflict sorta came to us, and it's pretty much the ideal scenario for it lol. We were never going to send troops. Never. Not a chance lol. While we may not want Ukraine to fall, we also don't consider them meaningful enough to risk fighting the largest war in 70 years to prevent it.
Lackluster Russian performance was pretty much the Ukrainian saving grace, as once Russian forces were de-facto halted, and it became very clear that the war wasn't going to be over any time soon, we figured "well, if they want to degrade the military capability of our scariest conventional land adversary, and all we have to do is keep them supplied with these weapons we have which are purpose built to do just that... hey that works out super great!" A borderline captive-actor Ukraine, who has to keep fighting for national survival, who is on the doorstep of the entire rest of NATO - and therefore can be supplied relatively easily, and who is a lot "closer to home" both literally and psychologically to many Europeans - who is successfully inflicting losses (at a meaningful scale) on the RuGF, all without a single drop of American blood being spilled... that's about as good as it gets lol.
This would not be the case in the WESTPAC. Firstly, there's no real "national survival' fight going on in Japan's case. They're our long time strategic partner, and they have their own interests which misalign with PRC aspirations in the region. Worst case scenario, they lose the Senkakus, which hardly compares to the butcher's bill that fighting the PRC would tally up. While I (and most folks here in DC) do operate under the assumption that they would join us if we were to intervene in a Taiwan conflict, they most certainly would require our meaningful, visible, active participation to have a *hope* of sticking it out longer than a few weeks once they start seeing warheads on foreheads. South Korea, those guys are a complete write off. Nobody here seriously considers them a likely partner in a PRC conflict, and there's a certain rotund individual residing to their North who is responsible for that. ROK participation would result in untold civilian casualties and infrastructural devastation at the hands of the - inferior, yes; but still capable enough to draw blood - KPA. This isn't even mentioning the generally more favorable relationship the PRC and ROK have compared to the... interesting diplomatic rapport between JP and the PRC.
Taiwanese asymmetric resistance, even as much as it's discussed, really isn't something we actually expect, if I'm being brutally honest.
Even if there's lots of talk about it, it's important not to see them just as an extension of US interests in the region. I know lots of folks on this forum see them as basically a US puppet; but I promise, you're overestimating how competent and coordinated we are lol. The ROC isn't suicidal. While it may be militarily beneficial for a US war effort for the ROCA to transition to guerrilla CONOPs, to fly modern "kamikaze" sorties to shoot down at most one PLAAF airframe prior to their own destruction, or to attempt to strike the least impractical targets... what the hell is it all for? In the US's perspective, sure, it makes sense - it's to tie town and degrade PLA forces, planning, admin, and staff capacity, and to help buy us time to marginally regenerate surviving 7FLT AOR forces, and to surge 3/5FLT naval forces, USAF forces, and USMC expeditionary forces. For them? It's not quite so clear. They send - at a minimum - dozens of smart, capable young men and women to their deaths in flying coffins, condemn hundreds more to burning, drowning, suffocating, or bleeding out in anti-shipping strikes at the outset of hostilities, thousands more will die in strikes on basing, C4ISR infrastructure, and other prompt operational fires. Should the PRC initiate the land component of the campaign, and if by that point the US has not been able to degrade the PLA counter-air/shipping complex sufficiently to interdict amphibious shipping and debarked forces, then thousands upon thousands more Taiwanese youth (remember, wars are not fought by hot ripped dudes like in movies. in the real world, most junior enlisted personnel are still pretty much kids, it's fucking scary when you notice it for the first time) will be killed and injured in a bloody, costly campaign of resistance against the PLA advance. The island will be without running water, without sewage treatment, without power, without communications, and will soon be without food, all the while. Many thousands upon thousands more will die fighting a *very* well organized and supported PLANMC/PLAGF amphibious land component force. Remember, in LSCO, it's fires that does all the killing, not the infantry. the infantry just does the dying. Despite all of this bloodletting, the PLA land component force *will* still be able to force Taiwan to bend the knee, unless the US can turn the tide.
It's at this point when you have to ask, what was it all for? OBVIOUSLY the ROC left unsupported stands no meaningful chance. The *only* way they would have a shot in hell at coming out the other side still an independent entity is if the US+JP forces can crack the PLA system of airpower sufficiently to prevent air interdiction over and east of Taiwan, and to destroy enough of the PLAN's maritime capability to allow critical supplies (at a minimum) to get flowing into the island again. Without this, Taiwan can simply be starved into submission if all else fails. The problem is, accomplishing these "guardian angel" objectives are simply, utterly, and completely outside of our military capabilities. It's not going to happen, to put it as bluntly as possible. As a result, from the ROC perspective, what's the point of pursuing such an asymmetric strategy, and enduring all of that bloodshed and hardship if they're just going to end up a PRC province regardless?
Exactly. None.
It's far better to procure a military that is at least able to assist, in any capacity at all, an effort to defend the island conventionally. Should that prove insufficient when combined with the US and JP intervention forces in theater at the outset of hostilities, and should the PLA make it to the beach, and establish debarkation points, it is far better to just throw in the towel and spare the 23 million citizens of Taiwan from such a horrific, fruitless, national self-immolation.
